Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a banknote depositing and dispensing mechanism in a recycling-type automatic depositing and dispensing machine.

(Prior Art) Automatic deposit and withdrawal machines that recycle banknotes have been put into practical use in financial institutions such as banks for the purpose of saving labor and improving capital efficiency. In this system, the banknotes brought by the customer and processed for deposit are used as banknotes for the next withdrawal, and the bank that installs this system prepares a large amount of banknotes for withdrawal in advance or during business hours. There will be no need. Therefore, it has the advantage of improving capital efficiency, and by incorporating this into automated teller machines (ATMs) that execute cash payment transactions by the customer's own operations, it is possible to save the labor of bank staff in charge of these deposit and withdrawal operations. The aim is to By the way, these recycling-type automatic deposit/withdrawal machines distinguish the withdrawals brought by customers and not only check whether they are genuine or false, but also whether they are valid tickets that can be reused for withdrawals or are damaged or dirty. The banknotes are sorted out from unsuitable and damaged banknotes, and only banknotes that are considered genuine and correct are stored in the banknote storage box for withdrawal.

However, as mentioned above, this recycle-type automatic deposit/withdrawal machine uses banknotes brought by the customer for withdrawal.
There have been cases of defective withdrawals due to bends, etc. That is, even if the banknotes brought by the customer are not found to be soiled or damaged, many of them have creases such as folds in two or folds in four.

Fig. 2 is an explanatory view of the main parts of a bill separating and feeding device to explain the problems of the conventional method, in which Fig. 2a is a sectional view and Fig. 2b is a plan view, which is a known method generally called a friction separation method. It is. This will be explained below.

In the figure, 1 is a storage box for stacked banknotes, and 2 is a stage that can be moved up and down with banknotes 3 placed thereon.When separating and feeding banknotes 3, the stage rises upward and the stacked banknotes 3 are placed on it. Roll the top banknote surface with Pitzcarroller 4.
press against. Next, as the picker roller 4 rotates in the direction of the arrow A, the top bill 3 is sent out along the guide member 5 in the direction of the arrow B by the frictional force between the picker roller 4 and the bill 3. Also,
For example, there is a method for separating and feeding banknotes.
There are some that use vacuum pressure, such as 112885. In this case, the mechanism corresponding to the picker roller 4 in FIG. 2 is a suction drum, and the top of the stacked banknotes 3 placed on the stage 2 is brought into contact with the circumferential surface of the suction drum, similar to the friction separation method described above. As a result, a vacuum force acts to separate and feed this in the direction of arrow B.

(Problem to be solved by the invention) However, in the conventional configuration described above, raising the stage so that the top surface of the stacked banknotes comes into contact with the surface of the picker roller as uniformly as possible improves the separating and feeding operation. It means to stabilize. For example, when there are multiple (in this case, two left and right) picker rollers as shown in Figure 2b, if a difference in the frictional force (or a difference in vacuum suction force) between the left and right picker rollers occurs, the feed will move in the direction of arrow B. The banknotes that are fed may be skewed or misspelled, and may even become jammed. That is, as shown in FIG. 2B, if the uppermost banknote does not come into even and sufficient contact with the circumference of the pick roller, sufficient reliability cannot be expected in the banknote deposit/withdrawal operation.

Furthermore, in order to increase the processing speed of these banknote depositing and dispensing mechanisms, it is a good idea to transport the banknotes in the lateral direction; Or the valley has a big influence. To be more specific, the top of the stacked banknotes 3 comes into contact with and is pressed against the guide member 5 for regularly transporting the banknotes to be separated and fed to the next process, and the banknotes are connected to the guide member 5 before being pressed against the surface of the roller 4. 3, the problem arises that the pressing force becomes too high. That is, the guide member 5 should be
Although it is made of a material with a small surface friction coefficient, a large stage lifting force is used to force the piled banknotes 3 to conform to the rollers 4 and guides 5 and press them flat. Therefore, when trying to separate and convey the stacked banknotes, the friction between the banknotes 3 or between the guide 5 and the banknotes 3 becomes too large, and since the pick roller 4 is fixed, a difference in tension between the banknotes 3 and the roller 4 occurs, or pressure is generated. There was a problem that the separation and feeding operation could not be performed stably because of excessive pressure. That is, this has led to poor separation such as skew feeding and double feeding during separation and feeding, which in turn has caused banknote jams and banknote tearing.

The present invention eliminates the problems of excessively high pressing force between the guide member and banknotes and unbalanced pressing forces between the banknotes and the left and right pick rollers, and enables stable separation and feeding. This aims to improve the reliability of the withdrawal operation of an automatic teller machine that reuses deposited banknotes brought by customers for withdrawal.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention is an automatic teller machine, which is arranged near the upper entrance of the safe, and stores deposited banknotes and dispenses out paid banknotes. In a banknote deposit/withdrawal mechanism, a plurality of guide members are each movable up and down independently to press the top surface of stored banknotes, and a plurality of rotation members are each movable up and down independently to feed out the banknotes stored. The guide member and the rotating body are arranged to be vertically movable independently of each other.

(Function) With the above-described configuration, the pick roller and the guide member are positioned so as to be able to move up and down independently according to the condition of the banknotes, so that when the banknotes are fed out when a large number of folded banknotes are accumulated, they are evenly distributed against the banknotes. It can give tension. Therefore, the above problem can be solved.

(Example) FIG. 3 shows a schematic configuration of an automatic teller machine to which the bill depositing and dispensing mechanism according to the present invention is applied. In the figure, the banknotes inserted into the deposit slot 6 are sent one by one to the verification section 7, where they are verified for authenticity and fitness. The banknotes that have been identified as genuine and authentic are conveyed as they are along the route 16, and are transferred to the conveyance path switching gate means 9, 1 according to the denomination.
Divided by 0, 11, 1,000 yen, 5,000 yen, respectively.
It is stored in each safe 12, 13, 14 of 10,000 yen. In addition, near the upper entrance of each of these safes, a banknote deposit/withdrawal mechanism 15 is provided which accumulates banknotes in the safe and feeds out banknotes one by one from the safe and sends them out to the conveyance path. On the other hand, the banknotes that are determined to be fake by the recognition section 7 are returned to the deposit slot 6 by the switching gate means 8. Further, banknotes that are true and are discriminated as unfit notes pass through a route 16 and are stored in a redirect box 17.

When withdrawing money, the banknote deposit/withdrawal section 1 on each safe 12, 13, 14 will be used for the amount specified by the customer.
The money is withdrawn from 5 and passes through the discrimination section 7. This identification section 7
At , the banknotes deemed to be normal are dispensed to the deposit slot 6 by the switching gate means 8, and the banknotes deemed to be defective due to heavy running, abnormal skew, etc. are transferred to the redirect box through the route 16 by the switching gate means 8. It is stored in 17.

Next, a bill depositing and dispensing mechanism which is an embodiment of the present invention will be described in detail using the drawings. FIG. 1 is a sectional view showing an embodiment of the present invention, and FIG. 4 is a plan view thereof. The banknote deposit/withdrawal mechanism has a payout port 18.
is formed, and a feeding roller 19 is provided opposite to this feeding opening 18 as an example of a feeding rotating body. A pair of left and right feed rollers 19 are provided, located on both sides of a certain width area at the center of the banknote, and the peripheral surface thereof is formed of a material having high frictional resistance all around. Note that the feed roller 19 may be replaced with a feed belt.

A gate roller 20 is provided opposite to the feed roller 19, and the gate roller 20 has a built-in appropriate one-way clutch so as not to rotate in the opposite direction, thereby preventing two bills from being fed. A pair of left and right picker rollers 21a and 21b are provided in the central part of the deposit/withdrawal section and are located on both sides of a range having the same width as the payout roller 19, and the left and right pair of picker rollers 21 and pulley 22 are fixed to a shaft 23. A pair of left and right belts 24a and 24b are stretched. The end of the belt 24 is connected to the feed pulley 2
5 is fixedly located on the rotating shaft 26. Further, the circumferential surface of the picker roller 21 is made of a material having high frictional resistance all around.

The shaft 23 to which the Pitsuka roller 21 is fixed is
It has a structure that is supported by a pair of left and right arms 27a and 27b, and is swingable about a support shaft. Also, springs 28a, 28 are attached to the arms 27a, 27b.
b is attached, and the picker roller 21 is biased in the downward direction, forming an independent suspension structure. A sensor 29 is also provided to detect the position of the picker roller 21.

The above-mentioned feeding roller 19 has an appropriate one-way clutch built therein, and is provided so as to rotate in the feeding direction. Further, power is transmitted to a pulley 30 on a fixed shaft of the feeding roller 19, a pulley 32 fixed on a motor shaft, and a pulley 33 on a fixed shaft of the pulley 25 through a belt 34. Pulleys 35 to 38 are provided in front of the feeding roller 19, and belts 39,
40 is stretched. The belts 39 and 40 are rotated in a discharge direction 41 by a motor (not shown).

A guide member 42 is provided adjacent to the picker roller 21 to regularly convey the bills to be separated and fed. Also, a shaped member supporting the guide member 42 is attached to the side plates 44 and 45.

A compression coil spring 43 is provided between the shaped member and the guide member 42, and this guide member 42 has three members 42a,
It is divided into 42b and 42c, each of which is movable up and down.

Many of the deposited banknotes are folded as shown in FIGS. 5a and 5b, but when they are pressed against the picker roller 21 and the guide member 42, the folded banknotes are folded as shown in FIG. The guide member 42 is located and presses against the banknote uniformly on both sides. For example, FIG. 5a shows the Pitzcarroller 21a,
21b and the center guide 42a are raised, as shown in FIG. 6a, and in FIG. 5b, the left and right guides 42b and 42c are raised as shown in FIG. 6b.

At this time, by reducing the spring constants of the springs 28 and 43 and reducing the change in tension with respect to deflection, P ₁ as shown in FIG.
≒P ₂ , P ₃ ≒P ₄ are realized.

The feeding section is provided with a sensor 46 that detects feeding of banknotes. These sensors are constituted by well-known photoelectric sensors.

Furthermore, to explain the storage mechanism, a roller 47 is provided in the storage opening opposite to the pulley 25 described above, and rollers 48 and 49 are provided above the roller 47. The stored banknotes are pinched by rollers 48 and 49 and fed onto the stored banknotes by belt 24, and aligned by picker roller 21 to the top row of stored banknotes.

Next, the operation of the dispensing mechanism configured as above will be explained. When the customer specifies the payment amount, a motor (not shown) in each safe is driven.
Stage 50 rises. The bill on the stage 50 presses against the pick roller 21, and the sensor 29 turns on.
When this happens, the feeding operation begins. At this time,
Even if the banknotes on the stage 50 are stacked with folded banknotes as shown in FIG.
1b has an independent suspension structure, and the guide member 42 on the ceiling has a swingable structure, so that the friction force between the left and right pick rollers 21a, 21b and the banknotes, and between the banknotes and the guide member 42 is uniform. It's summery.

Next, the picker roller 21 and the payout roller 19 are rotated by the separation motor 51 ON, and the banknote on the uppermost side is sent out to the payout port 18 . In the event that a large number of banknotes are delivered to the payout port 18, the gate rollers 20 function to separate them into one banknote.
When the separated bill is conveyed to the first sensor 46, the separation motor 51 is stopped. After stopping for a specified time and conveying the banknotes by the belts 39 and 40, the separation motor 51 is turned on again to feed the next banknote, and this operation causes the number of banknotes corresponding to the amount specified by the customer to be turned on again. , repeated in each safe.

(Effects of the invention) According to the invention detailed above, the following effects can be obtained.

(1) Since the Pitzcarroller has an independent suspension structure and the guide member on the ceiling has a swingable structure, even bills in poor condition on the stage, such as folded or wrinkled bills, can be evenly pressed on the left and right sides. Therefore, stable separation and feeding operation without skew or double feeding can be performed.

(2) By making the pressing force between the guide and the banknotes uniform, or between the Pitzcarroller and the banknotes,
There is no need to increase the torque of the stage drive motor, and the motor can be made inexpensive, lightweight, and small.
